We previously proposed that interferon-α plays a crucial role in premature vascular damage in SLE. IFN-α alters the balance between endothelial cell apoptosis and vascular repair mediated by endothelial progenitor cells (EPCs) and myeloid circulating angiogenic cells (CACs). Here we demonstrate that IFN-α promotes an antiangiogenic signature in SLE and control EPCs/CACs, characterized by transcriptional repression of IL-1α and β, IL-1 receptor 1 and vascular endothelial growth factor A (VEGF-A) and upregulation of IL-1 receptor antagonist (IL-1RN) and the decoy receptor IL1-R2. IL-1β promotes significant improvement in the functional capacity of lupus EPCs/CACs, therefore abrogating the deleterious effects of IFN-α. We used microarrays to analyze the effect of IFNα on peripheral blood EPCs/CACs and on bone marrow EPCs exposed to proangiogenic stimulation. Overall design: Human healthy EPCs from bone marrow were isolated and cultured under proangiogenic stimulation after IFNa incubation or not, RNA was extracted and processed for hybridization on Affymetrix microarrays."],"tag":["xref:PubMed:20805419","xref:PubMed:22058412"],"repository":["ENA"],"description_synonyms":["Yellow Marrow, data, human being, Man (Taxonomy), medullary bone, medulla of bone, STGD4, Modern, Antigen AC133 homolog, MCDR2, ER-PM contact site, Prominin-like protein 1, endoplasmic reticulum-plasma membrane contact junction., Prom-1, man, PROM1, AC133, human, RP41, antigen AC133 homolog, CD133, Red Marrow, Human, prominin-like protein 1, Prom, antigen AC133, Antigen AC133, Homo sapiens, PROML1, medulla ossium, CORD12, ER-plasma membrane contact site, Modern Man, Marrow, medulla ossea, MSTP061, Red, 4932416E19Rik, Yellow, Man, Proml1, Bone, EPCS"],"name_synonyms":["Human, Modern., human being, Man (Taxonomy), Homo sapiens, man, Man, human, Modern Man"],"additional_accession":[]},"is_claimable":false,"name":"Homo sapiens","description":"Expression data from human healthy CD133+ bone marrow EPCs","dates":{"last_updated":"2025-09-24","first_public":"2014-02-11"},"accession":"PRJNA136957","cross_references":{"GEO":["GSE26951"],"taxon":["9606"],"PubMed":["20805419","22058412"]}}
